As soon as we try to think of the nature of constructive building in terms of a letting-dwell, we come to know more clearly what that process of making consists in by which building is accomplished. Usually we take production to be an activity whose performance has a result, the finished structure, as its consequence. It is possible to conceive of making in that way; we thereby grasp something that is correct, and yet never touch its nature, which is a producing that brings something forth. For building brings the fourfold hither into a thing, the bridge, and brings forth the thing as a location, out into what is already there, room for which is only now made by this location.
